Mori have started to conduct a portion of the polling over mobiles, though they don't think it makes any difference.Something else to bear in mind about the 'official' polls: they are usually carried out by the polling company phoning a landline. An awful lot of poor people (and young people) don't have landlines because they cost too much. They just have a PAY-G mobile.

There’s a slight methodological tweak in this month’s poll – for the first time MORI conducted a proportion (20%) of the interviews via mobile phone. Past testing by MORI over the last five months suggests this doesn’t actually make any difference to the final figures, but it avoids a potential future risk.
